When collecting data on catheter-associated urinary tract infection (CAUTI) bundle compliance, what rate should an infection preventionist expect from the collected data?

• A. Point prevalence
• B. Incidence rate
• C. Cumulative incidence
• D. Attack rate

Answer: (A)

The main idea is how adherence to a care process is quantified. For CAUTI bundle compliance, you’re measuring how often the recommended practices are actually used at a given moment, which is a snapshot of performance. This yields a point prevalence—the proportion of eligible opportunities (like catheter-days) where the bundle was correctly implemented at that time. It’s a snapshot of current practice, not the rate of new infections over time or the risk of developing an infection. For example, on a particular day there are 60 catheter-days and the bundle was followed on 50 of them, giving a point prevalence of compliance of 50/60 (about 83%). If you were counting new infections over time, that would relate to incidence, not this process-compliance snapshot.
